Neco 2020 Physics Question 4
Practice essay / theory question 4 from the 2020 Neco Physics examination. This question covers forces, Newton's laws, friction .
A 5.0 kg crate rests on a horizontal floor. The forces acting on the crate are shown in the force diagram. The tension in the rope is 20 N and makes an angle of 30° above the horizontal to the right. A horizontal push of 5 N acts to the right on the crate. An additional upward force of 5 N is applied vertically. The weight of the crate is due to gravity (g = 9.8 m s⁻²). The crate moves with constant speed under these conditions. The coefficient of kinetic friction between the crate and the floor is unknown. Answer the following:
